    Ubuntu Security Notice USN-1990-1
    October 17, 2013
    xorg-server, xorg-server-lts-quantal, xorg-server-lts-raring vulnerabilities
    A security issue affects these releases of Ubuntu and its derivatives:
    - Ubuntu 13.04
    - Ubuntu 12.10
    - Ubuntu 12.04 LTS
    The X.Org X server could be made to crash or run programs as an
    administrator if it received specially crafted input.
    Software Description:
    - xorg-server: X.Org X11 server
    - xorg-server-lts-quantal: X.Org X11 server
    - xorg-server-lts-raring: X.Org X11 server
    Pedro Ribeiro discovered that the X.Org X server incorrectly handled
    memory operations when handling ImageText requests. An attacker could use
    this issue to cause X.Org to crash, or to possibly execute arbitrary code.
    It was discovered that non-root X.Org X servers such as Xephyr incorrectly
    used cached xkb files. A local attacker could use this flaw to cause a xkb
    cache file to be loaded by another user, resulting in a denial of service.
    Update instructions:
    The problem can be corrected by updating your system to the following
    package versions:
    Ubuntu 13.04:
      xserver-xorg-core               2:1.13.3-0ubuntu6.2
    Ubuntu 12.10:
      xserver-xorg-core               2:1.13.0-0ubuntu6.4
    Ubuntu 12.04 LTS:
      xserver-xorg-core               2:1.11.4-0ubuntu10.14
      xserver-xorg-core-lts-quantal   2:1.13.0-0ubuntu6.1~precise4
      xserver-xorg-core-lts-raring    2:1.13.3-0ubuntu6~precise3
    After a standard system update you need to reboot your computer to make
    all the necessary changes.
